HOT-AIR FURNACE.

SPECIFICATION forming part of Letters Patent No. 730,202, dated June 2, 1903.

Application filed February 19. 1903. Serial No. 144,035. (No model.)

To all whom it may-concern:

Be it known that I, JOHN M. BEECH, a citizen of the United States of America,and a resident of Cincinnati, in the county of Hamilton 5 and State of Ohio, have invented certain new and useful Improvements in Hot-Air Furnaces, of which the following is a specification.

This invention relates to certain improvements in furnaces, and has for its object to improve and simplify the constructionand arrangement of the furnace-front, so thatthe same is made capable of complete removal in a simple and convenient manner, whereby a I material saving both of time and labor is effected when it is desired to remove the furnace-front for the purpose of repairing the furnace or for other reasons, and it is rendered unnecessary to dismantle the furnace 2o altogether in such cases' The invention consists in certain novel features of the construction, combination, and arrangement of the several parts of the improved furnace whereby certain important 2 5 advantages are attained and the device is made simpler, cheaper, and otherwise better adapted and more convenient for use, all as will be hereinafter fully set forth.

The novel features of the invention will be 0 carefully defined inthe claims.

In the accompanying d'rawings,which serve to illustrate my invention, Figure 1 is a front elevation showing a furnace embodying my improvements; and Fig. 2 is a perspective View showing the front portions of the improved furnace, the doors of the furnace-front being shown in opened position to disclose the interior arrangement. Fig. 3 is a view similar to Fig. 2, but illustrating the furnace 0 with the grate-front removed to illustrate the means for supporting the same when in position for use. Fig. 4. is asectional view taken vertically through the feed-section and illustrating in side elevation the means carried thereon forsupporting the grate-front. Fig. 5 is a detached perspective view showing the combined grate-front and dead-plate of the furnace. b

As shown in the views, 1 indicates the firebox of the furnace, and 2 indicates the ashpit thereof, while 3 indicates as a whole the I external shell or casing of the furnace. The furnace to which the invention is applied may be of any kind; but as herein shown the improvements are applied to a hot-air heatingfurnace.

4 indicates the grate, which divides the firebox from the ash-pit and supports the fire,

'for dividing its upper part from its lower part; butsaid section is continuously open from top to bottom, as'shown in Fig. 3 of the drawings. 1

6 indicates a dead-plate which is extended transversely and horizontally across the u pper part of the feed-section 5, and the fuel is adapted to be supplied to the fire-box above this dead-plate in feeding the fire. The deadplate 6 is removably supported in the feedsection 5 upon side rests or projections 7 7, integrally formed upon the opposite side portions of said feed-section, and saiddead-plate is alsointegrally formed with the grate-front 8,which,'as shown in Figs. 2, 4, and 5, is'extended vertically downward from the rear edge of the dead-plate and has its lower edge provided withv integral pendent projections or lugs 9 9, the lower ends of which are adjacent to the forward edge of the grate 4, said lugs 9 being spaced apart topermit the insertion of a poker between them for stirring the fire and for the ready discharge of ashes. The lugs at the ends of the series 9 9 are madein greater length, as shown at l0 l0 in.the drawings, and are bent slightly forward and adapted to rest upon the horizontal portions of L- shaped or angular stops or auxiliary rests 11 11, integrally formed upon the opposite side portions of the feed-section 5 below the rests 7, which extend under the ends of the deadplate 6.

ends of the grate-front 8 are arranged to extend down in front of the vertical parts of The extended lugs 10 10 on the IOO the L-shapcd stops or rests l1, and said rests or stops serve to prevent the grate front from kicking up or being pushed or forced upward when the fire is being stirred or stoked.

12 indicates a depending flange or lip extended along the front edge of the dead-plate (5 and adapted when said dead-plate is supported on the rests 7 to extend down in front of the forward ends of said rests in such a way as to prevent the dead-plate and gratefront from being pushed or slid rearwardly into the fire-box. The rear ends of the rests 7 are also formed with angular downwardlybent extensions 13, adapted to take against the front of the grate-front 8 to prevent the same from warping and also to hold the combined grate-front and dead-plate solidly in place in the feed-section 5 and obviating draft at those poi n ts.

The feed-section is provided with a plurality of doors for closing its open front, and said doors are arranged one above another and are all hinged, as herein shown, at the one side of the feed-section, although this is immaterial to the invention. The dead-plate 0 is also arranged to stand in a slightly-inclined position when in place in the feedsection.

14 indicates the central door of the feedsection, and 15 indicates the upper door thereof, which latter when opened affords access to the fire-pot above the dead-plate for charging or stirring the fire. 16 indicates the lower door of the feed-section, and this when opened gives access to the ash-pit below the grate 4, so that ashes may be conveniently removed therefrom. The doors 14:, 15, and 16 are arranged in such a way that their meeting edges are closely adjacent when the doors are closed, so that the open front of the feed-section may be tightly closed when desired, and the lower door, as herein shown, is provided with a damper 17 of any preferred kind.

The rests 7 7 at the sides of the feed-section 5 afford a secure and firm support for the ends of the dead-plate and the auxiliary rests or stops 11 11 prevent tilting or kicking up of the grate-front and dead-plate when in place in the furnace, and at the same time it will be obvious that said combined dead-plate and grate-front may be conveniently and readily lifted out of the feed-section when desired, so as to afford free access to the fire-box and ash-pit through the large opening of the feed-section, so that repairs may be very quickly and conveniently made. The central door 14 of the feed-section may be left closed at ordinary times and will be opened only when repairs are to be made and it is desirable to have free access to the interior of the furnace through the full opening of the feed-section. When it is desired to have access to the fire-box or to the ash-pit, the upper or lower doors l5 and 16 may be opened independently of the central door.

The furnace constructed as above described is of an extremely simple and inexpen sive nature and is especially well adapted for use, since the structure of the front thereof affords very convenient access to the interior for making repairs, and since there is no obstruction whatever within the feedsection when the doors thereof have been opened and the combined dead plate and grate-front have been removed it will be seen that the repairs may be effected in a much quicker time than in furnaces as heretofore constructed. Since the front of the fire-box is also most liable to burn out and require repairs, it is evident that the removable grate-front which forms the front portion or wall of thesaid fire-box considerably lessens the expense of repairs and permits of their being more easily made. It will also be obvious from the above description that the furnace is capable of considerable modification without material departure from the principles and spirit of the invention, and for this reason I do not wish to limit myself to the precise form and arrangement of the several parts of the device herein set forth.

Having thus described the invention, what I claim, and desire to secure by Letters Patent, is-- 1. A furnace having a grate dividing its interior into an upper fire-box and a lower ashpit and provided with a feed-section having an opening extended from its upper to its lower part, the upper part of the opening affording access to the fire-box and the lower part thereof affording access to the ash-pit in combination witha grate-front and a deadplate extended transversely across the opening in the feed-section and removably supported therein, substantially as set forth.

2. A furnace having a grate dividing its interior into an upper fire-box and a lower ashpit and provided with a feed-section having an opening extended from its upper to its lower part, the upper part of the opening affording access to the fire-box and the lower part thereof affording access to the ash-pit, said feed-section having side portions formed with integral. rests and a dead-plate extended transversely across the opening of the feedsection and having its ends removably supported upon the rests at the sides of the feedsection, substantially as set forth.
